transaction-id 和 clientid 全是 0 是我模糊处理了

同网络爱快倒是能拿到 IPv6

是不是 ISP 的模板问题？如果是的话该如何有效的和 ISP 反馈？

同站有类似案例

@yulihao 不知道是不是同一个问题

[flynaj]

RouterOS 配合问题， 光猫是 openwrt 的系统，要丝滑还是上 openwrt,RouterOS 是构建在 Linux 上的闭源系统。

一样的症状

讨论过好久的问题了，7.18 开始 ros 已经增加了 Validate Server DUID 选项，取消勾选就行了

@Ruslan 取消勾选 Validate Server DUID 还是拿不到

从日志上来看没有看得 bad server DUID ，暂时先排除，Validate Server DUID 保持取消勾选就行
DHCPv6 Client 的配置发一下
确认勾选的是请求 prefix ，并且长度正确。部分地区可能/56 ，/60 都有

[xqzr]

clientid 全 0 ？也许不合法
